Main research interest is assessment of occupational exposures for occupational epidemiology and industrial hygiene.

Areas of active research involve:

• Development of a job-exposure matrix using expert ratings of occupational exposures made during several population-based case-control studies of cancer in the Montréal general area.
• Creation of a retrospective occupational exposure databank for the province of Quebec using measurements made since the 1980s by governmental hygienists in this province.
• Exploitation of publicly available databases of retrospective industrial hygiene measurements.
• Statistical modeling of occupational exposures using modern methods (e.g. multimodel inference, Bayesian models) to help indentify determinants of exposures.
• Knowledge translation of current start of the art statistical approaches to comparing measured exposure levels to occupational exposure limits.
• Design and evaluation of performance of sampling strategies in industrial hygiene.
